Description
Technical field
The present invention relates to the novel stirring drivings that a kind of graphite keeps the temperature sand.
Background technology
Graphitizing furnace feeding temperature-raising is to after 2900 DEG C, and heating process is completed, into cooling stage.Isostatic pressing formed graphite product is given birth to
Produce the period in, heating process is generally 10~15 days, and cooling technique process, for avoid cooling down it is too fast cause damage of product, can
Up to 30 days or so.Heating process is limited by the production requirement of properties of product, and adjustment space is smaller, and cooling technique in addition to
Need stringent control outer in critical process point, process is more shorter better, and there are larger elastic adjustment spaces.
It is high to temperature requirement due to being graphitized during being graphitized feeding temperature-raising, using 0~1mm granularities point in stove
The petroleum coke powder of cloth carries out efficient insulation effect as heat preservation sand to furnace body, prevents heat from largely conducting outward.But this layer is protected
The high-efficiency insulated effect of warm sand is the biggest obstacle of cooling technique, and therefore, the groundwork of cooling technique is exactly to remove heat preservation sand,
Reinforce furnace body thermal diffusion, shortens the cooling time of graphitizing furnace.
Currently, most of domestic graphitization workshop is directly caught heat preservation sand using grab bucket, it is placed in independent cold burden storehouse
It is cooling.The major advantage of the cooling means is：Red heat heat preservation sand is directly caught, radiating rate is fast, and the cooling cycle is typically about
20 days.But there are shortcomings for this method：1 material grasping process operating difficulties, it is difficult to accurately control, be easy to cause product oxidation；2 grab
It needs to configure independent cold burden storehouse outside stove after material；After 3 heat preservation sand are placed in external place, since heat preservation emery dust material granularity is distributed as
0~1mm, it is difficult to all recycle, form duration waste；4 material grasping processes need to drive a vehicle and personnel have coordinated on furnace body
At there are security risks.
Invention content
In view of the above-mentioned problems, the present invention provides the novel stirring driving that a kind of graphite keeps the temperature sand, background is efficiently solved
The problem of being pointed out in technology.
The technical solution adopted by the present invention is：
A kind of novel stirring driving of graphite heat preservation sand, including cross bar, be fixed with below the both ends of the cross bar it is a pair of with
The bottom of the orthogonal montant of cross bar, the montant is equipped with a pair of of pulley, and the lower section of the pulley is equipped with to match with pulley
Slide bar, the pulley driven by pulley motor, and the montant is equipped with a stirring axis, institute in the other end relative to cross bar
The both ends for stating stirring axis are linked with two montant rotations respectively, and the outside cambered surface upper edge axial restraint of the stirring axis has multiple turn over
Expect bar, a driven gear coaxial with stirring axis, the lower section setting of the cross bar are fixed in the middle part cambered surface of the stirring axis
There is a driving gear to match with driven gear, the driving gear is rotated by chain-driving driven gear, described
Driving gear is driven by gear motor, and the gear motor is fixed on the lower section of cross bar, and the stirring axis is internal water storage
Hollow structure, the side cambered surface of the stirring axis is equipped with multiple with the fog-spray nozzle being connected inside stirring axis, the stirring
One end of axis is connected by rotary joint with water inlet pipe.
Preferably, the both ends of the stirring axis are connect by bearing with montant, inner ring and the stirring axis of the bearing
Fixed, outer ring and the montant of the bearing are fixed.
The present invention by the stirring bar on stirring axis to heat preservation sand carry out it is lasting stir, to accelerate keep the temperature sand heat dissipation
Rate realizes the purpose that graphite is quickly cooled down, and realizes that the movement in horizontal direction, fog-spray nozzle are sprayed by pulley and pulley
Mist can greatly improve cooling effect, improve cooling rate.
